Abstract

An oil-field high-temperature acidification corrosion inhibitor was synthesized through Mannich reaction by using formaldehyde,acetophenone and aromatic amine.Weight-loss method,electrochemical method and SEM were used to investigate the compound property and inhibition efficiency of this inhibitor.The results indicated that when the the molar ratio of formaldehyde,acetophenone and aromatic amine was 4∶2∶1,the inhibition efficiency of Mannich compound was good.
